BOX.

Application tiled April 12, 1922. Serial No. 551,854.

i like and consists of the matters hereinafter the box after it is packed.

and handling and makes a desirable box for the packing of such articles as soap and the like.

The improved box requires a minimum of stock and may be made at low cost for material and labor. Its several advantages will appear more fully as I proceed with my specification.

In'the drawings Figure 1 is a perspective view ofthe improved box;

Figure 2 is a view representing a partial section through the box, in a plane indicated by the line 2-2 of Fig. l; v

Figure 3 is a plan view of a blank for making the body of the box; and Y Figure 4 is a plan view of the blank for the ends of the box.

Referring now to that embodiment of the invention illustrated in the drawings 10, 10 indicate the sides of the box; 11 the bottom of the box; 12, 12 the ends of the box, and 13 the top closure, comprising in this case two over-lapping iiaps 13, 13a.

The body of the box is made, as shown, from an elongated blank (see Fig. 3) of approximately a width equal the length of the box. This blank is cut and creased to provide the part l1 for the bottom of the box, two parts l0, 1() at each side thereof for the sides of the box and two extensions 13, 13, comprising the flaps, for the top clos-ure 13 of the box.

The blank is creased transversely by lines 14 to define. the several parts mentioned. The blank is also creased longitudinally by parallel spaced lilies 15 which define the length ot the several box-forming parts, except the top closure flaps' 13, 13, said lines terminating at their point of meeting with the crease lines 14 defining the folding lines of the flaps 13a, 13a. The blank has lateral extension parts which are cut and creased to provide short folding end extensions of the two side parts and the bottom part 10, 10L and 11, -It also has lateral parts 13" which provide end extension parts of the top closure fiaps 13, 13a.

The ends of the box each consist of a blank of plan area equal to the cross-sectional area of the box and of a top flap cxtension 12a defined by' a crease line 12". The flap extension 12El of the end part 12 as well as the extensions 13b of the top closure parts 13a are inclined at their ends as indicated, respectively, at 12c and 13.

To form the box, the blank (shown in Fig. 3) is bent into form with the bot-tom i 11 horizontal and the sides 10, 10 in vertical relation; the blanks for the ends 12 are in succession brought into the required relation with their edges coinciding with the crease marks 15 of the main blank; and the extensions 11 and 1.0, respectively, of the bottom and side-forming parts of the blanks are bent a ainst them (as shown-- against the outer aces of said end blanks) and are then attached together either by stapling or other well-known, familiar manner. This puts the box in condition for loading, with the flange extensions 12 on the end vertical (but ready to be folded back) and with the top cover iaps 13, 13 laidV back to open up the box.

The box is then loaded. After loading, the closure flaps 13"L vare turned down, the one over-lapping the other, against the flap extensions 12a, 12a of the ends of the box, which are folded down in the process of folding down the top closure flaps. The

top closure flaps are then stapled, sealed or attached in any convenient manner to the end flaps 12a Which'stand outwardly, away lmeans which operate entirely outside of and beyond the horizontal plan dimensions of the box. Thus it is possible to place boxes of the kind as they are loaded, upon Aa belt which will feed or present the boxes as they are-loaded, to a stapling or other machine of the kind, in rapid and continuous succession, where the only requirement of the machine is that it shall secure together' in two parallel spaced lines comparatively thin fibre or paper-board parts.

The folding extensions 12 which provide the seats for the top closure and the end extensions 13b of said top closure, provide, after they are attached together, projecting end hand holds or grips at the top of the box, which are convenient in lifting and handling the box. By reason of the inclined parts 12 and 13 at the ends of the respective extensions 12n and 13b, projecting corners are eliminated.

If desired and perferably, the top closure flaps are sealed or attached together where they overlap along a line 13, as by staples.

I'Vhile in describing my invention I have referred to several details of construction and mechanical arrangement, it is to be understood that the invention is not thereby in any way limited except as may be pointed out in the appended clalms.

I claim as my invention 1. A box of libre, paper-board or the like having sides, bottom, ends and a top closure, the ends having top flap vextensions adapted to be folded into the plane of the top of the box, and the top closure having extensions adapted to seat upon and to be secured to the flap extensions of said ends.

2. A box made of blanks of fibre or paperboard or the like, comprising a blank cut and creased to provide a bottom, sides and a top closure flap,`-the sides, bottom and top closure flap having end extensions, and blanks cut to form the ends of the box and having top extension flaps; said first-named blank heilig folded to form the main body of the box and having the end extensions of its sides and bottom folded upon and secured to the sides and bottoni parts of the said end blanks, and the extensions at the top of ysaid end blanks being adapted to be folded down to form seats in theplane of the top of the box to receive and to be attached to the extensions of the top closure I of the box.

il. A box of fibre, paper-board or the like made from the main blank, cut and creased to provide bottom and sides and top closure flaps, said bottom and sides and said l top closure flaps having end extensions and from blanks for the "ends of the box, each having a foldable flap extension at the top; the end extensions of the bottom and sides of the main blank being adapted to be folded against and secured to the marginal parts of the end blanks, and the foldable flap extensions at the top of the end blanks being adapted to be folded down to provide seats in the plane of the top of the box for the attachment of the end extensions at the ends of the top closure flaps.

In testimony that I claim the foregoing as my invention, I aflix my signature this 5th day of April, A. D. 1922.
